Yeah, that cold snap is brutal on DEF systems. We're seeing the same thing in Michigan. Had a Ford F-250 last week where the DEF line cracked right at the injector. The heaters just can't keep up when it gets that cold for that long. It feels like the parts they're using now are cheaper than they were a few years back.

But is your brain really that picky about what counts as a break? I just close my laptop when I'm done for the day, no fancy calendar tricks needed. Seems like overthinking it to me.

You said it becomes way easier to keep up with. What was the hardest part to get into that routine at first?

That study lines up with what I've seen. More coolant isn't always better and can actually cause issues like residue and skin irritation. A refractometer is the only way to know for sure what you're running.

Honestly, covering the ground is the whole point. You set a goal and you meet it, that's the real satisfaction. Stopping to stare at a creek just turns a solid hike into aimless camping.
